I Claims. This invention relates to the lifter motion of spinning machines such as are used for the twisting or doubling of yarn, such as ring-spinning, flyer-spinning and cap-spinning machines.

5 In machines of the above type, the spindles are generally arranged substantially vertically and the traversing of the yarn being spun upon the bobbins or other yarn packages is effected by the vertical movements of a lifter rail which carries either the bobbins on which the yarn is being wound' or guide means for conducting such' yarn to the bobbins. These vertical movements are effected by means of vertical lifter rods each actuated by a chain attached to the lower end of the rod, the chain passing over flanged wheels or chain sprockets and being secured to a horizontally reciprocating traverse rod. Each lifting chain is secured to one side of the lower end of its lifter rod, and through the chains is transgo mitted the whole of the force necessary to raise the lifter rail and the various elements mounted thereon. On account of the lateral connection between the chains and the lifter rods, the rods are submitted also to a bending moment which is liable to cause deflection of the rods and to give rise to faulty spinning, especially in machines adapted to operate at a high speed. It is an object of the present invention to provide an improved spinning machine which is free from the disadvantage outlined above.

According to the present invention, lifter rod members are employed which are of such section that each lifting chain may run up the axis of the lifter rod member to which it is attached.

By the-term axis is meant the line joining the centres of area of successive cross-sections of the lifter rod. member. In one convenient form, a circular rod is employed which is deeply grooved longitudinally so as to receive the chain. Since 40 the pull of each chain is along the axis of the lifter rod member (hereafter referred to as lifter rod) to which it is attached and the rod is submitted to a compressive force only, the bending force arising from a lateral attachmentof chain 4.5 to rod is avoided.

the provision of two traverse rods connected together at suitable intervals by yokes to which the ends of the chains are attached between the rods. Thus the lifter rods, lifting chains and sprockets therefor are mounted between the two traverse 5 rods, and any bending force which might be applied to the traverse rods is taken by the yokes which transmit to the traverse rods a purely tensile or compressive force.

The invention is of particular advantage in 10' connection with the method of mounting the traverse rods described in U. S. application S. No. 36,954 filed August 20, 1935, corresponding to British application No. 26,638/34 filed 17th September, 1934, and with the method of actuating 15 the traverse rods described in U. S. application S. No. 36,955 filed August 20, 1935, corresponding to British application No. 26,639/34 ;cording to the present invention will now be described in greater detail with reference to the an accompanying drawing in which Fig. 1 is a front elevation of a cap-spinning machine provided with means according to the invention and Figs. 2 and 3 are a front elevation and a. sectional side elevation of the lifter rods according to the in- 35 vention, and Fig. 4 is a detail of Figs. 2 and 3.

A cap-spinning machine according to the invention comprises a fixed horizontal spindle rail l. Stationary spindles 2 are secured to the spindle rail at suitably spaced intervals by means 40 of an attachment 3 as described in U. S. specification S. No. 36,953 filed August 20, 1935, corresponding to British application No. 26,635/34 filed 17th September, 1934. ,The spindle rail is constructed in sections secured to the frames 4 of the machine. At the upper ends of the spindles 2 are the caps 5 of the machine, and surrounding each of'the spindles 2 is a driving wharl I driven by a band 8 and mounted in suitable bearings in a horizontal lifter rail 9: The wharls 1 drive the bobbins l0 provided for the reception of the yarn to be spun. I

The weight of the lifter rail 9 and of the bobbins l0 and associated parts mounted thereon is taken by a number of vertical lifter rods I l which l3 situated below the spindle rail 5 and mounted,

as described in U. S. application S. No. 36,954 flied August 20, 1935, corresponding to British application No. 26,638/34 filed 17th September,

1934, upon rocking quadrants id to which they .are secured by metal tapes it. each lifter rod l l is deeply grooved longitudinally,

as shown in section in Fig. 4, for the reception of a chain it which is secured to the bottom of the rod l! by means of a screw ll' fitting into a nut it which is of greater diameter than the rod, and is recessed on its upper side to receive the end of the rod 1 6. An additional nut i9 is provided beneath each nut it to serve as a locking means.

The lifting chains it pass centrally up the rods ii and over sprockets 20 disposed between and a little below the traverse rods it, their upper ends being secured to yoke's 2i by means of which the two traverse rods it are connected together at intervals.

A screw 22 connects the chain it to the yoke it, which is secured to the rods 23 bya clamping piece 23 and nuts and bolts 2:3.

The traverse rods l3 are reciprocated horizontally by means of suitable lever and cam arrangements, such for example as described in U. S. application S. No. 36,955 filed August 20, 1935,,corresponding to British application No. 26,639/34 filed 17th September, 1934. One such arrangement is shown on the right hand side of Fig. 1 in which a lever 25 rocks about an adjustable pivot 26 provided with a Vernier scale 2? to facilitate adjustment of the length of traverse. The lever 25 is actuated by a cam 28, and its upper end is connected to the traverse rods 53. The lever 25 alternately pulls the chains i6 so as to raise thelifter rail 9 through the medium of the lifter rods H and allows the chain 56 to return so that the lifter rail 9 descends again. In order to counter-balance wholly or in part the weight carried by the lifter rail 9, counter-balance weights may be employed, or, with advantage,

. Patent 15 Z compressed air cylinders may be provided at the ends of the traverse rods it as described in 11.8.

application S.No.36,955 filed August 20,l935,corresponding to British application No.' 26,636/34 flied 17th September, 1934. The cylinders are connected to a suitable reservoir'of compressed air and assist the operating cams 28 in forcing the traverse rods 83 in one direction so as to lift the lifter rail i-l. In the other direction of traverse the weight of the lifter rail 9, the elements I? and the bobbins it carried thereby maintain the traverse rods E3 in engagement with the cam 28, and recompress the air in the cylinder. Alternatively, the cam 23 may be made to operate in the other direction so that it acts with the weight of the lifter rail 9 to compress the air in the cylinder, the cylinder alone effecting the raising of the lifter rail 9.
